To all whom, it may concern:

Be it known that TAPLEY W. YOUNG, a

I citizen of the United States, residing at \Vash agency provided toarrest the concussion imparted to ington, in the District of Columbia,have in-j vented certain new and useful Improvements in Dynamite Shells;and I do hereby declare the following to be a full, clear, and exactdcsc'ript-iou of the invention, such as will enable others skilled inthe art to which it appertai'ns to make and use the same. My inventionrelates to projectiles of the class designed to contain a charge ofhighlyexplosive compound, such as dynamite, and

the metallic shell by the initial charge before it hasibeen communicatedto the dynamite, else there will be great'dang'er of an explosion of thelatter before theshell is ejected from the cannon.

To provide a vessel forv containing the explosive compound which willnot be subject to the dangerous effects of undue concussion resultingfrom theexplosion of the charge of gunpowder behind the shell in whichthe vessel is placed is the objectotmy invention, which consists-in thenovel construction and arrangement of parts, which will first be fullydescribed in connection with the accompanying drawing, and-then clearlypointed outin theclaims. a i

In thedrawing, which is a vertical section of a shell containing myimprovement, A represents an ordinary metallic shell. v

Bis the vessel for containing the explosive compound, preferablybottle-shaped, as shown.

0 represents the outer casing of the vessel B, the said casing being ofa size and shape to snugly fit the bore .of the shell. j

D D represent annular rims connecting vessel'B and easing 0, beingpreferably formed integral with those parts, and through these rims, atsuitable intervals, are perforations d, for a purpose which willformed,- integral with one of the annular rims, and is made somewhatthicker than the rim, as seen in the drawing, so as to, offer greaterresistance to diaphragm E. 3

The space between the bottom of the vessel and the bottom of thebore-ofthe shellis (iii vided. by a diaphragm, E, joined to the casing, thusleaving an air-cushion, F, in the bottom of the shelL- r The vessel,casing, rims, and diaphragm are In fitting the shell for use these partscan be when they will at once expand and assume their proper forms.

The mouth of .the shell and also the inouth all made'of elasticmaterial, such as rubben the air driven against it by the dcflection'of.I

compressed sufiiciently to enter at the mouth,

of the vessel are closed by a metal screw-,

plug, A, the lowerend of which is considera blyv reduced in diameter,and over'this reduced portion is fitted a rubber stopper, G. The flangeb around the mouth of thevessel takes into a recess, a, in the top ofthe shell, over which is placed an annular ring,"H, flush with the topof the shell,'for securing thefvessel at that point.

Rearwardly inclined perforations I are formed through the uppcrs'portionof the shell and easing, as show perforations preferably correspondingin num her with the perforationsin each of the rims D.

The 'desired quantity u in the-drawingfthese.

of dynamite or other I like'explosive compound having'be 'p e presentlyappear. 5o The bottom of vessel B is charge of powder. When theexplosion of the powder takes place, the concussion innparted to thebottom of the shell causes an impactof the airin the cushion againstdiaphragm E, which, beingelast-ic, is thereby deflected in a mannershown in dotted line.

This sudden deflection drive the air above of the diaphragm will itoutwardly and 11pwardly through the'perforations d outside and aroundthe vessel 0, when-it will escape from not. be filled full, the compoundwould of course have motion within it, and therefore,

theshell through perforations '1. Thus there .will be no such impact onthe vessel at any,

explosion of its contents. Should the vessel to avoid itscomingin'conta'ct with any hard 1' '2 v assess substance, I have attached therubber stopper -'end of the perforation communicating. with.

to the metallic screw-plug. Y

In order to render the explosion of the dynamite or other like compoundcertain, I prefer to use a fuse of some description, that which 'I haveillustrated being a desirable one on acthe chamber is placed what may becalled a" .plu-nger, .m, having a nipple formed upon it for carrying ape'rcussion-cap.- The chamber is closed at the top by a screw-plug, a.When ters Patent, is-

the shell strikes, the plunger is by its momentumv thrown against theplug a with sufficient forceto explode the cap, whereby fire is communicated to the powder forming the fuse,

the explosion of which will detonate the dynamite.

. Having thus described my invention, what I claim as new, and desire tosecure by Let- 1. Incombination with a metallic ordnanceshell, anelasticcasing' fitting the bore of the shell,"an inner elastic vessel,and perforated annular rims connecting the vessel with the casing,- forthe purpose above set forth.

2. In combination with a metallic ordnanceshell, an elastic casingfitting the bore of the shell, an inner elastic vessel, and perforatedannular rims connecting the vessel with the .ing the body of. the

casing, the bottom of the vessel being thicker than and formed ,integralwith one ofsaidrims, for the purpose stated.

1 3. In combination with a metallic ordnanceshell, an elastic casingfitting the bore-of the shell, a bottle-shaped inner elastic vessel, theneck of which is attached to the casing, and annular elastic perforatedrims connectsubstantially as described.

4. In combination with a metallic ordnanceshell having rearwardlyinclined perforati ons in its forward end, an elastic vessel hav-' ingan outer perforated casing adapted to fit the bore of the shell, thevessel and easing connected by perforated annular rims, and a vesselwith the casing,

diaphragm extending across the casing below the vessel, substantially asdescribed, and for the purpose set forth.

5. In combination with a metallic ordnanceshell havingrearwardly-iuclined perforations 1n itsforward end, an elastic, casingfitting the bore of the shell, an inner elastic bottlewith arubberstopper,

shaped vessel provided perforated elastic an n ulai rims connecting thevessel with the casing, a diaphragn'i extend ing across the casingbelowthe vessel, and means for detonating the contentsof the vessel,substantially as described, and for the purposes above set forth.

In testimony Whereof I afiix my signature in presence of two witnesses.
